Type 1 surge arrester / DIN rail - max. 150 kA | DE
The DE is a Type 1 AC Surge Protection Device (SPD) dedicated to be connected at the entrance of the electrical installation. Particularly useful in a high lightning density area, this SPD is designed to provide protection for sensitive equipment against over voltage due to lightning effects or industrial interferences. In association with DGU, DGR or DGV surge arresters (see diagram), the DE surge arrester provides common and differential surge protection for AC networks, following the CT2 configuration in IEC 60 364-5-534 standard.Protection is based on specific high energy gas tube which provides much lower residual voltages and very high discharge current capability on a 10/350 μs or 8/20 μs impulses.
